This hex nut is manufactured to DIN 934 specifications and made from steel with an electro-galvanized finish, making it suitable for indoor use or applications with very mild exposure conditions. The nut features metric threading and is machined (turned). Please note: Class |6| nuts are rated according to DIN 267-4 and have a lower load capacity than Class 6 nuts rated under ISO 898-2. Mechanical overloading can cause the threads on the nut or bolt to strip.
